The invention provides an engine oil pump control method and device and an engine. The method comprises the steps that an oil discharge instruction indicating that an engine oil discharge switch is inan opened state is obtained; a check three-way valve in the engine is controlled to be switched to an oil discharge position, the first end of the check three-way valve is connected with an oil inletpipeline of an engine lubricating system, the second end of the check three-way valve is connected with an output pipeline of an electric control oil pump of the engine, and the third end of the check three-way valve serves as an oil discharge outlet of the engine and communicates with the exterior; and the electric control oil pump of the engine is controlled to start, so that oil liquid in theengine is discharged through the oil discharge outlet of the check three-way valve. In the oil discharge process, a user only needs to trigger the oil discharge switch to complete discharging of the oil liquid of the diesel engine, the user does not need to participate in subsequent operation, the process is simple, and labor is freed.
Description
technical field [0001] The invention relates to the technical field of engines, in particular to an engine oil pump control method, device and engine. Background technique [0002] When the vehicle runs for a certain mileage, the engine needs to be maintained. At this time, the residual oil in the engine needs to be drained. In the prior art, in the process of engine maintenance, the engine is usually drained by hand pump mechanically. Oil work, the whole process requires the user to participate in the whole process, a waste of human resources. Contents of the invention [0003] In view of this, the embodiments of the present invention provide an engine oil pump control method, device, and engine to solve the problem of wasting human resources during the engine oil discharge process in the prior art. [0004] In order to achieve the above purpose, embodiments of the present invention provide the following technical solutions: [0005] A method for controlling an engine o...
